The FBI is investigating a hacking incident where someone breached a Cumberland Valley School District computer network with student and employee records.

Superintendent Dr. Frederick Withum said authorities do not believe the hacker viewed confidential information, but the district is not 100-percent certain that no personal data was accessed.

Administrators were notified of the breach Thursday.

The district has hired a forensic specialist and anticipates an audit will be completed within the next week. Any public findings will be shared with the community, according to a statement on the district’s website, http://www.cvschools.org/.

In the statement, administrators said it appears the breach was the work of an outside hacker in Eastern Europe who used the CV server as a pass-through to store information.

Withum said swift and immediate action was taken to protect the confidential information of students and staff. He said the district will continue to evaluate security procedures.
